Aneurysms cocaine abuse

Cocaine abuse is a risk factor for myocardial ischemia, infarction, and dysrhythmias, as well as pulmonary edema, ruptured aortic aneurysm, infectious endocarditis, vascular thrombosis, myocarditis, and dilated cardiomyopathy (35). 

Cocaine abuse is a risk factor for myocardial ischemia, infarction, and dysrhythmias, as well as pulmonary edema, ruptured aortic aneurysm, infectious endocarditis, vascular thrombosis, myocarditis, and dilated cardiomyopathy (32). Acutely, cocaine suppresses myocardial contractility, reduces coronary caliber and coronary blood flow, induces electrical abnormalities in the heart, and increases heart rate and blood pressure. These effects can lead to myocardial ischemia (33,34). However, intranasal cocaine in doses used medicinally or recreationally does not have a deleterious effect on intracardiac pressures or left ventricular performance (35).
